n GEM SETTING.

Application lec'l December l0, 1921.` Serial No. 521,508.

To all whom t may concer/n:

Be it known that I, JosnrH F. DONAHUE, a citizenof `the United States, residing at Providence, in thecounty of Providence and State ofRhode Island, have invented certain new and useful Improvements in Gem Setting, of which the following is a specilication. y

This invention relates to a jewelry component, `more particularlyY to an improvement in the construction of settings for i gems, and the' objeetof this invention is to form such a gein-setting of a channeled member in which the edges of the side walls of the channel are beveled to provide a seat for gems,'and the edges of the walls formed thin and adapted to bebent over the opposite edges of the gems to bind them in the setting.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings.

Figure .l is a face view of the gem-setting showing the hollow or open-centered frame or body having a channeled outline into which the gems are set.

Figure 2 is a face view of the sheet stock cut into` the desired outline and having its center punched out, the dotted lines showing the 'width of the `channel where the side y walls are drawn up to form the channel.

Figure 3 is a greatly enlarged top view showing a portion of the channeled frame.

Figure 4 is a greatly'enlarged section on line 4--4 of Figure 3. showing the edges as beveled and formed thin and so adapted to be bent over the edges of the gem.

`Fipuire f3 shows the gem supported on the `beveled side of the frame with the edges of the latter bent thereover to bind the gems in the setting.

The old method of forming n'iulti-sided f settings of the channeled frame type was to saw "grooved wire ordinarily carried in stock, into sections and solder their mitered y ends together but this was found to be too 50 expensive and did not produce a finished article. The nent method was to try to bend a length of this channeled, stock wire or strip, but this was found to be quite impractical owing to the fact that bending the 55. wire into multi-,sided figures having sharp angles, the wire became crushed and its walls greatly distorted. As the first method of forming in section is too expensive, and the` second is quite impracticable particularly where the devices are made small I have provided a new construction of channeled frame or body which is produced by drawing up a single piece of sheet metal, in a single operation, having a continuous cha-nnel and forn'ied complete without the use of solder, which construction has manyadvantages over the structures formed by the old methods, and the following is a. detailed description" of one form of 'my improved device Viith reference to the drawings, l0 designates a hollow or open-centered frame or setting which is constructed from a sheetmetal blank 11, see Figure 2, that is first cut from sheet stock into the desired outline with its center' l2 removed. This blank is then struck with a hollow tool, shaped in outline similar to that shown in dotted lines 13 in this Figure 2 and when struck with this tool the side walls 14 of the frame or body are drawn up as illustrated in Figure 4 forming a continuous channel completely around the frame into which the gems l5 may be set. i

The inner edges 16 of the walls of this channeled frame are preferably beveled as best illustrated in Figure 4, and these edges are formed very thin to be readilybent. The beveling of these edges may be produced by first striking the edge of the blanks if desired before being drawn up in channel form, or these edges may be beveled by run-` ning a cutting tool about them, or any other suitable means for beveling may be employed. Y

In mounting the gems in this channeled setting, I iirst deposit the gems one at a time into the channel with the `edges of the gern resting against the beveled edges of the comparatively thin side walls 14 as shown in dotted lines in Figure 4, I then turn the eX- tremely thin edges l? of the side walls over the edges ofthe gems firmly securing them in the setting. y

These gems by my improved construction may be slid along on their beveled seat in the channel so that their edges will closely contact with each other producing the appearance of a continuous blaze of brilliancy completely about the whole setting.`

I have shown a channeled setting of octagon shape but the same may be formed in any desired shape in outline.

By my improved construction a setting may be struck up very rapidly and where the edges are formed thin by a swaging operation, when the blanks `are 'dropped from the press they are practically complete and ready to receive the gems, and when so set they are extremely strong and durable and yet handsome and attractive in appear- GUCE.

The :foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the priif'ilege ot resorting to all the mechanical changes to which the device is susceptible, the invent-ion being del-ined and limited only by the terms ot' the appended claims.

I claim:

l. A gem-setting comprising a continuous seamless integral channel traine formed of sheet stock with a bottom portion and two opposite substantial parallel bendable side walls standing upwardly therefrom form ing a continuous channel, whereby gems of varying diameters may be longitudinally adjusted while being set to cause their margins to closely abut, the edges of said walls being provided with a continuous beveled seat torl stand upwardly from said bottom toi-ming 1 a continuous channel, the inner edges of said walls having a continuous bevel along their length to provide a continuous seat on which the gems may rest and be longitudinally ad- `insted in setting, the outer portions of beveled edges being formed thin to be readily folded over the edges of the gems to bind them in setting.

In testimony whereof I affix my signature.

JOSEPH F. DONAHUE.
